DISK-SLED ATTACHMENT.

Specification of Letters Patent.

Patented Nov. 9, 1915.

Application led 'February 7, 1914. Serial N o. 817,205.

To all whom t may concern:

Be it known that I, LAMY A. GAUME, a citizen of the United States, and aresident of Danville, in the county of Harper and State of Kansas, haveinvented certain new and useful Improvements inl Disk-Sled Attachments,of which the following is a specification, reference being had to theaccompanying drawings, forming a part of this specification.

This invention relates to improvements in disk sleds and comprises anautomatic attachment by means of which the soil, in the use of the disksled, is cross harrowed, the furrows made by the disks beingyimmediately closed while the ground is leveled, thus conserving themoisture, while eliminating the furrows.

Another object is to provide a disk sled with a time and labor savingattachment, that can be readily secured to al disk sled, expediting theworking of corn, Kafir, cane, cow peas, or any other listed work.

IVith these and other objects in view, the present invention consists inthe combina tion and arrangement of parts as will be hereinafter morefully described and finally pointed out in the appended claims, it beingfurther understood that changes in the specie structure shown anddescribed may be made within the scope of the claims, without departingfrom the spirit of the invention.

In the accompanying drawings forming a part of this specification, andin which like numerals of reference indicate similar parts in theseveral views: Figure 1 shows a side elevation of a disk sled providedwith my attachment, the leveling knives being shown eut of workingposition in dotted lines. Fig. 2 is a top view of Fig. 1. Fig. 3 is aside elevational view showing the tension lever thrown into workingposition. Fig. 4: is a view showing in detail one set of knives andtheir connections, a broken portion of the rock shaft also being shown.Fig. 5 shows an enlarged sectional detail of the two part tensionspring. Fig. 6 shows a broken detaildisclosing the members securing thetension leverI to the tension bar. Fig. 7 shows a broken detached detailof one of the bearing ears and collars.

In my present invention I provide an automatic disk sled attachment,comprising'a set of spring held drag knives,.the position of which canbe accurately adjusted and which are carried by a holder the tension ofwhich can also be adjusted land regulated so that where a field isworked comprising a dry, tough, cloddy heavy gumbo soil, the

knives are held more stiii'iy than where used in light, mellow, moistloose or sandy soil.-

The knives operate to level the soil immediately after the passageofthedisks so that there is no loss of moisture, and this leveling ofthe soil prevents washouts and the packing of the soil through rain.

In the drawingsthe numerals 1, 1 represent two suitable sled runners tothe forward ends of which aresecured the side bars 2, 2 by means of thebolts 3. Secured near the rear end to each runner 1 by means of a bolt lare the ends of the U-shaped frame 5 this frame being further braced bymeans of the bracebars 6 secured by means of the bolts 7 and 8. A seatis fixed to this frame 5. i

As shown in Fig. 3, each side bar 2 is provided with a U-shaped shackle9, suitably secured thereto, and held upon the upper edge of each bar 2,by means of a shackle 9 is a disk shaft 10, provided with suitablecutting disks 11. At their inner ends these disk shafts 10 are connectedto a bolt a, from which extendsthe connecting rod 12.

HeldA upon the upper edges of the side bars 2 is the cross bar 13 whichis secured by means of thefclipsflt-which engage the bars 2,'as shown nF igs.; 1 and 3; Secured to this cross bar 13, is a gear sector 15carrying a pivot pin 16 giving support'to the operating lever 17 whichis connected by means of the pin 13 to the connecting rod 12. By meansofthis lever 17 the disks 11 are adjusted. This-lever, 17 is provided witha suitable detent as is .usual in lever construction, the detent beingarranged for co-action with the gear sector 15. Further secured t0 thecross bar 13 is the gear sector 20 to which is operatively connected theadjusting lever 21 having a suitable'detent or thumb latch arranged forco-action with the'gear sector 20. To this adjusting lever 21 is securedthe connecting rod 22 which. has its upper ends suitably secured to theU-shaped frame 5. Secured to this cross barrl3ris the s draw bar 23carrying a suitable ring o, at

its end to which the draft animals are connected.

Secured to each ofthe side bars 2 byl end having a slotted head 26. Thisstandard is braced by means of the rod 27 secured by means of the bolt2S to the upwardly curved end of the side bar 2, as clearly shown inFigs. l and 3. Secured to the rear upstanding end of each side bar 2 bymeans of a bolt 23 is a counter-part carrying bar 30 each having one endslightly curved as is shown in Figs. 1 and 3. At their forward endsthese carrying bars 30 are secured by means of bolts 77., to thestandards 25, 25. At its rear end each carrying bar 30 has secured to ita bearing ear 3l one of said ears being shown in detail in Fig. 7, andthese bearing ears are arranged to revolnbly receive the bearing collars2, each having a stop shoulder 3, and a setbolt 3. Securely held withinthese bearing collars `2 is a square rock shaft 32 to which are securedin parallel spaced relation, but in staggered position the trailingknives'A, A and B, B. As shown in Fig. 2 one of the carrying bars issecured to the end of the opposite side bar 2, by means of a connectingrod f.

As shown the knives A and A which are po sitioned below the knives B, Bare shorter than the knives B and B', all of said knives being curved,the knives A and B curving in a direction. however opposite the knives Aand B, as shown in Fig. 2. IThese knives are adjustably secured to therock shaft. The knives A and A are each secured to an offset knifeholder 34 shown in detail in Fig. 4, and within the socket 35 of eachholder the knives are held by means of suitable bolts and nuts and (3.These bolts pass through suitable slots c, within both the holder andthe knife, so that these knives are adjustably secured to their holder.Each holder 34 has a head 36 having a square opening to receive theshaft 32, the holders being secured by means of set bolts 3. Held inspaced relation to the offset holders 34 are the holders 37 having thesockets 33 within which are held the slotted ends of the knives B, thebolts 5 land nuts G being used to adjustably hold these knives B to theholders 37 which are also provided with slots fu, as shown in Fig.v 4.The knives A and B curve in. one direction, while the knives B and Acurve in opposite directions, the two longer knives B, B being heldadjacent one another.

Secured zto the rock kshaft 32 is a crank arm 33 which is held to therock shaft 32 by means of a set screw 3 and this arm 33 at its upper endcarries a bolt 7 as shown in Figs. l and 3, and this bolt in turn givespivotal. support to the apertured tension lever 40 which is adjustablysecured to the bolt 7. Near what forms its inner end the bar 40 isprovided with a stop head 41 having the lip e, which is arranged toengage over the connected tension bar 43, the head 4l having anoperating handle 42 as clearly shown in Fig. 6. The tension bar 43 ispivotally secured to the lever 40 by means of the bolt 8 and thistension bar 43 at its forward end is provided with a slotted socket 44,within which is held a two part spring comprising the intertwining coils53 and 54.l

slot of the head 26 is a bolt 59 which passes through the lever 50 andgives'support to a Wingnut 51, so that bymeans of this bolt 59 and nut5l the set lever 50 can be locked to the standard 25 in regulating thetension of the members 46, l43 and 40. The length of the springs 53 and54 can be adjusted in screwing or unscrewing the members 53 andl 54toward or away from one another, thus regulating the tension of thespring.

In going to or from a field, the tension lever 40 is thrown out ofengagement with the tension bar 43, thus permitting the knives beingthrown upward into a vertical position, as shown in dotted lines in Fig.l.

As shown the attachment is simple and inexpensive in construction, andboth durable and efficient in operation, and the tension of the knivesmay be regulated with ease, accuracy and despatch to meet the conditionof the soil.

Having thus described my said invention what I claim as new and desireto secure by S. Letters Patent is:
